What Is This Tool?
This converter helps you transform radiation absorbed dose measurements from millirad, a traditional unit, into decigray, an SI-derived metric that aligns with modern medical and environmental radiation assessments.
How to Use This Tool?
-
Enter the numerical value in millirad you wish to convert
-
Select millirad [mrd] as the input unit and decigray [dGy] as the output unit
-
Click the convert button to see the result in decigray
-
Use the provided examples for guidance if needed
Key Features
-
Converts absorbed radiation dose values from millirad (mrd) to decigray (dGy)
-
Utilizes a precise conversion rate for accurate unit transformation
-
Supports dose reporting for clinical, environmental, and occupational contexts
-
Browser-based tool requiring no installation
-
Provides example conversions for user reference
Examples
-
10 millirad [mrd] is equal to 0.001 decigray [dGy]
-
500 millirad [mrd] converts to 0.05 decigray [dGy]
Common Use Cases
-
Converting small or historical X-ray dose values into modern SI units
-
Reporting and comparing low-level environmental or occupational radiation exposures
-
Calibrating and specifying radiation survey meters and dosimeters that use legacy units
-
Expressing radiotherapy fraction doses and treatment dose increments clearly
-
Documenting intermediate clinical absorbed doses with finer granularity
Tips & Best Practices
-
Always verify the context to choose the most appropriate unit for dose reporting
-
Use this converter to standardize legacy rad-based values into SI units for better comparison
-
Refer to the examples section to understand practical conversions before entering data
-
Be aware of the unit limitations when dealing with very low or very high dose values
-
Cross-check conversion results when precision is critical for clinical or calibration use
Limitations
-
Millirad is a non-SI legacy unit that may involve rounding during conversion
-
Decigray may be too large for very low-level dose measurements where microgray is preferred
-
Accurate conversions depend on understanding legacy and SI unit equivalences precisely
Frequently Asked Questions
-
Why convert from millirad to decigray?
-
Converting from millirad to decigray allows expressing legacy or small absorbed radiation doses in a modern SI unit better suited for clinical and radiotherapy contexts.
-
Is millirad an SI unit?
-
No, millirad is a legacy unit from the CGS system and is not part of the International System of Units.
-
When should I prefer decigray over gray?
-
Decigray is useful for documenting dose increments or fractions in radiotherapy where finer dose granularity than gray is needed.
Key Terminology
-
Millirad [mrd]
-
A legacy CGS unit of absorbed radiation dose equal to one thousandth of a rad, used mainly for small absorbed doses and historical measurements.
-
Decigray [dGy]
-
An SI-derived unit representing one tenth of a gray, used for specifying absorbed radiation doses with finer granularity.
-
Absorbed Dose
-
The amount of energy deposited by ionizing radiation per unit mass of material.
